UDK Kjeldahl distillation units

The UDK Series distillers are designed to meet the most challenging demands and requirements for diverse applications, according to international standards: Kjeldahl nitrogen TKN, proteins, ammoniacal nitrogen, nitric nitrogen (Devarda), phenols, TVBN and volatile acids, cyanides, and alcohol content. Five different UDK models are available with different automation levels to match any laboratory requirement of automation and throughput. A complete range of distillers featuring exclusive technologies to meet any laboratory requirement for the determination of analytes in different fields of application.

• Ensures resistance and reliability with the exclusive VELP technologies
• Features an intuitive interface ensuring ease-of-use and data management at its best
• Guarantees excellent precision and accuracy
• Boosts efficiency in the lab with the connectivity option to VELP Ermes Cloud Platform
• Supports accessories for smart operations

The UDK distillers address any laboratory requirements from few samples per day to unattended operations with different level of automation for NaOH, H2O and Boric Acid addition. The regulation of the steam power (10 - 100%), dedicated accessories and premium technologies ensure a wide application range for diverse analytes in diverse industrial fields.

The UDK distillers are equipped with a full range of sensors and safety systems designed for maximum operator protection. The patented steam generator, patented titanium condenser and the technopolymer splash head provide maximum resistance and low maintenance, reducing the cost of ownership.

The UDK distillers guarantee reproducible results with an RSD ≤ 1% and are able to recover more than 99,5% of nitrogen. With a Limit of Detection of 0,015 mg N the UDK are the perfect solution even for challenging low nitrogen applications. The multitasking software with its intuitive user interface guides the operator step by step throughout the analysis. The 7” display ensures easy operations and the multiple connectivity options widen the possibilities of workflows optimizations.

The barcode technology streamlines routine operation for Kjeldahl analyses. The exclusive connectivity to VELP Ermes Cloud Platform (LAN cable or WIFI) projects your lab from time-consuming manual operations to a data-rich environment with premium remote service support.
